.....do i have to do anything speacial to use them or will they just replace my on stock ones(bolt right in)?

 

Should bolt right in <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

 

I was under the impression that they had to be torqued down differently than the stock GM bolts, due to the fact that they don't stretch. Someone who's used them before should confirm this though.

 

The ARP bolt are stretch to yeild bolts. They say on the instructions to torque them with an angle gauge. If you don't have on ARP say's to torque them to 45 ft lbs then loosen and repeat three times. I did this with mine then just checked them one last time.
